This wasn't exactly this simple. In the end, Texas gave him over around $1.5M over three years so money played a factor for sure. Tennessee simply decided it was not worth it in terms of potentially losing the locker room. NIL is not simply a bidding war between every program, as some assume it is. Some programs have a certain value on a kid and they won't exceed it.. Lots of things play into those decisions, such as 'What is my best player at this position making? Should I pay this transfer kid more and possibly upset the kids I have?' Those questions get very interesting when the kid coming in is not a sure thing. There are programs that are paying whatever it takes to sign kids, Tennessee is not one of those places, at least not right now while trying to build a new culture and foundation. However, everyone at Tennessee knows that if it is ever truly needed, their pockets are as deep as anyones. They will spend on kids they deem worth it, which won't be as many kids as Texas A&M for example. (The $30M signing class is 100% true for a fact)
Playing at Texas close to family certainly played a factor but the kid was also very enamored by the prospect of playing in Tennessee's offense.
